horizontal, lobed and parenchymatous thallus, from which many 

 plants arise. The details are well shown in the series of figures 

 of this species on plate 18. The figures are drawn from speci- 

 mens from near Pacific Grove, California, where one of us had 

 the opportunity of studying a very complete series of stages of 

 growth. But evidence that these plants are not exceptional in 

 this respect has been obtained elsewhere in California and on the 

 Alaskan Coast. The existence of a similar horizontal thallus in 

 Chordaria flagelliformis is suspected by us, at least in a more or 

 less reduced state (of., e.g., No. 482, P. B.-A., G. flagelliformis f. 

 densa Farlow) and likewise in Myelophycus ccespitosus Kjellman, 

 (according toKjellman's figure, 1893, f. 1, and Okamura's speci- 

 men, 1899, No. 44). The horizontal thallus of Analipus fusi- 

 formis Kjellman seems very similar to that of C. abietina. 



Analipus fusiformis Kjellman. 



In the lower literal zone, on rocks. St. Paul Island, Alaska, 

 Greeley and Snodgrass , No. 5795! . Townsend, No. 5782! (Setchell, 

 1899, p. 591). 



The plants included under the present species seem to agree 

 with the description and figures of Kjellman's plant from Bering 

 Island on the other side of the Bering Sea. The basal portion 

 is not very conspicuous, but is as marked as in the type. 

 Kjellman has placed this genus with Gmpidium J. Agardh in a 

 special section of the family Chordariacese on account of the 

 possession of a horizontal thallus, but, as shown above, this 

 character is found also in Chordaria abietina and perhaps in 

 other species as well as in Myelophycus easpitosus Kjellman.

Harvey says that Dr. Lyall collected a single specimen of this 

 species in fruit, which agrees well with British specimens. It 

 seems strauge that none of the collectors in this region have 

 seen it since.
